Hey Everyone,

Booked my car into Pitlane next week for a tune and injectors (can't wait!) and want to make sure my car is running spot on before it goes on the dyno.

First question is what spark plugs should I be running as it will be tuned to ~10 psi?

I have done the following / will do the following is there anything else I should do beforehand? Car is a 2003 BA XR6T with 65,000kms

*changed oil + filter

*serviced the K + N air filter

*fuel filter has been changed around 20,000kms ago (but will most likely change it again)

*change spark plugs

*will get manifold / turbo bolts tightened

*will get the auto serviced

sounds like a pretty good list mate, maybe clean the boost soleniod and throttle body depending on how many k's the car has done

Edit: id check all your intercooler hose clamps etc too

make sure you get the manifolds nipped up like you said!

.8mm gapped spark plugs is the general consensus. I bought the pregapped NGK but a lot of people prefer to gap the original ones IIRC?

obviously not crucial to your tune but when was your diff oil changed last? when I dropped mine at 26,000kms it was awful, I just did it again last week at 45,000kms and it was very clean still but thought I would do it anyway. something to consider if you are having a dirty weekend with your car.

I would like to buy the plugs already gapped, but been looking on the NGK website and looking at plugs for the BF XR6T they are gapped to 0.9 with the part number - BKR6EIX-P. I couldn't find any listed that were gapped to 0.8, which ones should I be looking for?

Throttle body clean and checking cooler hoses will be added to the list for the weekend too. Diff oil has been done fairly recently.

NGK BKR6EIX should already be pre-gapped at .8. I've got a set in my F6 and didn't have to touch a thing (though I did measure just to be sure).
